Versuchsvorschrift

A mixture of 1,1-dimethoxy-N,N-dimethylmethanamine (5.0 g, 41.96 mmol) and 1,1-dimethoxypropan-2-one (5.0 g, 41.96 mmol) was heated to 80° C. for 16 h. The solvent was removed under reduced pressure to afford 4-(dimethylamino)-1,1-dimethoxybut-3-en-2-one as a black colored liquid. The material was used without further purification.
